A self-levelling compound is a chemical mixture whose main use is filling dips in wooden floors, smoothing uneven concrete floors and serving as subfloors before the addition of final coverings such as stone, carpet or ceramic tiles. It particularly comes in handy when preparing floors for tiling, as even surfaces are key for ensuring the tiles don&#;t crack. Self-levelling compounds can be used in a variety of situations &#; from levelling a wonky floor in your kitchen, basement, garage, etc. to encasing underfloor heating prior to laying tiles.

Floor levelling compounds can vary depending on the specific situation they need to be used for, but overall there are two main types &#; acrylic-based levelling compounds and water-based levelling compounds. In addition to these, many manufacturers produce specialised levelling compounds in an effort to target different surface needs. Sikafloor Proseal, for instance, is a great curing agent, surface hardener and dust proofer for concrete.
The acrylic-based self-levelling compound requires mixing the powder with a liquid polymer to form the finished compound. Meanwhile, water-based self-levelling compounds come ready-mixed and only require the addition of water before they are ready to use. Because of how easy it is to prepare and work with, the latter is widely preferred for DIY jobs.
Latex self-levelling compounds are latex-based compounds often used for jobs where extra strong adhesion and pre-gauged liquid are needed. Using a latex self-levelling compound means you are working with a stronger mix which provides a limited degree of movement capability in the subfloor. Latex self-levelling compounds also help minimise installation risk in construction projects.
The thickness of self-levelling floor compounds tends to range between .04 and .4 inches, making them well suited for both indoor and outdoor jobs. Floor levelling compounds can be installed either by hand or with the use of a special mixing pump.
There are a number of advantages to using a self-levelling compound such as the Sikafloor Level 30. For one thing, it is incredibly easy to apply &#; as mentioned above, if you&#;ve got ready to use mixture you don&#;t need any special tools to apply the self-levelling compound. In fact, it can be applied fairly effortlessly in the space of 10 to 25 minutes, depending on the size of the floor area covered and the compound brand.
What&#;s more, the time it takes for the self-levelling compound to dry once it&#;s been applied doesn&#;t tend to exceed 24 hours. And since most levelling compounds are flexible and moisture-resistant, they provide a smooth, bump-free surface without the need for any further surface finishing. Last, but not least, thanks to how easy it is to use self-levelling compounds, the DIY enthusiast can save money on hiring a professional for the installation.
Floor screed is a type of self-levelling compound that usually contains latex, due to the need to retain its flexibility once it&#;s been laid and be able to move without any cracks appearing. One such self-levelling compound is Sikafloor Level 131, which is ready to use and perfect for smoothing and levelling out uneven internal floors. Once the screed has been mixed and poured in a very thin layer on the floor, it flattens out and self-levels.
The term floor screed is usually used to describe a mixture of cement and sharp sand which is used for creating a sub-floor that is both hardwearing and smooth. Despite the fact that the screed is made up of simple materials, the process of ensuring the floor is sturdy and level is actually rather complex.
Since a correctly laid floor screed brings a number of benefits, such as prolonged lifespan and improved quality of the floor, as well as the protection of the sub-layers from erosion and wear, it is imperative that it is laid by a skilled professional.
Depending on the setting, floor screed can either be left as the final floor finish (which can then be easily painted) or serve as an underlay that is then covered with decorative flooring such as carpet or tiling. Underfloor heating and pipework can also easily be accommodated by a screed.
There are a number of different types of floor screeds available in the market, that target a range of applications. One of the most common types of screed is the traditional screed &#; a standard mix of sand and cement suitable for finishing floors for a selection of coverings such as laminate and tiles, which can be used in many settings varying from schools and homes to shops and hospitals.
Floor levelling compounds are more expensive than standard floor screed mixes, but they are also the most efficient when it comes to ensuring that areas are level. This could be especially handy in spaces such as warehouses and industrial buildings where uneven floors could be a safety hazard.
Accelerated screeds, as the name suggests, are fast drying screeds that do away with the need to wait for weeks, or sometimes even months, for the screed to dry before proceeding with the final layer of flooring. With a drying time as short as three days, accelerated screeds are the ideal solution for completing projects on a tight deadline.
Self-leveling concrete is a strong, concrete-like flooring compound that's gained popularity in the U.S. in recent years. Unlike traditional cement, self-leveling concrete flows easily and levels itself over old flooring materials, broken concrete and other uneven surfaces. Due to these properties, self-leveling concrete is most often used as an under-layer before laying other flooring materials on top, such as vinyl or tile.

However, since self-leveling concrete is durable and cost-effective, many home and business owners wonder whether they can use the concrete layer as flooring itself. In this article, Portamix explains what you should know about self-leveling concrete, especially if you want to use it as a finished floor.
What is Self-Levelling Concrete?
Self-leveling concrete looks and functions much like traditional concrete but, when mixed using the correct self-leveling mixture, it flows much easier, allowing it to fill cracks, dips and imperfections on the foundation below it. Once fully spread across a surface, it takes about two hours to set and six hours to dry completely. Self-leveling concrete contains high volumes of polymers, which allow it to bond to itself and the material beneath it. While self-leveling concrete is more expensive than traditional concrete, it can save you time and labor by removing the need to replace existing, damaged flooring and creating level floors as soon as it's poured. As soon as it dries, you're ready to install new vinyl, tile, hardwood or carpet on top.
Common Applications of Self-Levelling Concrete
Self-leveling concrete is a useful, cost-effective solution to concrete issues in most homes and buildings. If you have damaged, cracked, pitted or splitting concrete in your home or business that is too substantial for traditional concrete patching, you can rely on self-leveling concrete to level your floors with ease. You can also use self-leveling concrete to fix uneven floors or an uneven foundation when the problem isn't severe enough to warrant mud-jacking or foundation repair. Finally, depending on the aesthetic or needs of your space, you may want to use self-leveling concrete as your finished floor. Thanks to its versatility and durability, self-leveling concrete leaves you with plenty of options for your commercial, residential or industrial space.
Can Self-Levelling Concrete be Used as a Finished Floor?
Self-leveling concrete can be used as a finished floor in most interior spaces. It's strong and durable, standing up to foot traffic and everyday wear and tear. Furthermore, there are countless coloring and finishing additives you can use to modify the look of self-leveling concrete to match your design aesthetic. Whether you own a home or a commercial space, self-leveling concrete can save you tons of money on repair and maintenance costs because it's easy to clean. Plus, if self-leveling concrete flooring gets damaged, you can always mix another batch and patch it up.
How to Install Self-Levelling Concrete
Self-leveling concrete only functions as well as it's installed, so you should have a professional mix and pour system to ensure a successful job. Portamix, for example, offers our Mega Hippo Mixer, a revolutionary self-leveling mixer featuring a powerful electric motor for thorough mixing capabilities, a closed-loop control handle to regulate pouring, and a sturdy frame with wheels for excellent maneuverability on site. A Mega Hippo Mixer mix and pour system helps to remove lumps and bumps from your self-leveling mixture, helping you achieve an even mixture and regulated pour, so you complete the job quicker and more accurately.
